DRAWER COMPANY, sYLvANrA.

Be it known that I, CHARLES M. CLARKE,

a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented cer- ,tain new and useful Improvements inColre- Drawing Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing,

forming part of this specification, in wh1ch- Figure 1 visa longitudinal sectional view ofa coke drawing machine embodying my im proved rake beam. Fig. 2 is a longitudinal vertical sectional view of my'improved rake beam for coke drawing ap aratus, partly broken away. Fig, 3;is a pl an view of the rear end of the-beam showing the cylinder for reciprocating therake. Fig. 4 is a partial sectional view similar to Fig. 1,showing the top of the rake thrown outwardly.

Fig. 5 is a similar view showing .the rake folded up underneath the beam in the position. assumed in'entering the oven. Fig. 6 1s a horizontal sectional view on the line view on an enlarged scale through the beam and its driving pinion, indicated by the line VII. VII. of Fig. 1. Fig. 8 is a cross sec 1 tional view onan enlarged scale through. the

front 'endof the beam, taken on the line VIII. VIII. of Fig. 2, the slide bar having been removed. Fig. 9 is a detail view shon ing a modification.

, My invention relates 'to apparatus'for" drawing coke from the oven, wherein a ciprocating beam having a rake or scraper headfadapted to be extended into and withdrawn from the oven toempty the'eonteuts therefrom. j

The present application refers more particularly to the construction of the beam carrying the scraper and to .the means forimparting movement to the scraper independent of the beam, or when the beam is stationary, and for positively extending or unfolding the scraper to operative position without a spring or'its equivalent.

The invention is particularly adapted for use with that class'of apparatus shown and described in the various patents issued to John A. Hebb, typical examples of which are embodied in U. S. LettersPatent Nos. 727790, 727942, 728101, 728102, and 749058.

Specification oi Lettera Patent. l v Patented June 1, 1908*. Application filed April 20, 1904,.Seriai No. 204,034. Renewed October 21, 1908. Serial No. 458,885.

Withdrawn from the oven, raised and lowered, adjusted laterally at varying angles to reach varying portions of the oven on the same horizonta plane, or bodily transported. from one oven to another of a series, refer: ence maybe had to the .above numbered patents. As the apparatus of the present lnvention, with'the exception of the beam itself, the rake and its actuatingmechanism, is identical therewith, I shall not particu- .darly describe'the machine as a whole except such of its elements as particularly relate to the beam. that the beam of this a ited to use with the Heb machine, but may be incorporated with. any other a paratus or combined with any other suitab e operating or traveling mechanism or structure.

Referring now to the drawings, the beam of angle shape or other desirable structural manneras by bolts or rivets, or by atop plate or upper portion 68 of any suitable form.

roller Or other guiding or bearing elements of the machine. Between the sides 67 is socured a toothed rack 69 of suflicient length the beam, with which raid; the driving pinion in one, direction or the other through the clutch controlled driving shaft 24. l

31 is the rake or scraper which is designed to be pivotally mounted at its top at the forward end of the beam to allow it to fold backwardly and upwardly toward the under side- Of' the beam in enteringover the top of the coke through the restricted opening of the door. The pivotal support or bearingof the top of therahe is adjustable back and forth independent of the beam, for which purpose I provide a piston 70 mounted in a cylinder 71, located atany convenient portion of the beam, as its back end. The cylinder is supplied at each end with steam, liquid, compressed air, or other suitable actuating mediumthrough pipes 7 2, 73, connected with a controlling valve 74 mounted. on the machine provided with the usual operating handle and connected with any source of supply, as a boiler 75. ble hose or tubing or.may be providedwith in which the rake beam is extended into and Itwill be understood however, hcation 1s not lim The pipes 72, 7 3, may be flex consists of vertical longitudinal sides 67, '67,

form, connected together in any convenient Such top element, if employed, provldes a good bear-mg for the upper bearing to give the necessary in-and-out travel of 25 engages, by which the beam is propelled the drawing operation.

fro movement ma be im arted to its u -er y end, This movement is desirable for the purpose of working the relatively stationary edge of the scraper'down into the crevices of the coke so as to cause it to engage a section before drawing it from the oven. It will be understood that during such manipulation of the rake, a downward pressure is being exerted on the beamby means of the rollers 66 or other suitable depressing mechanism.

Any suitable actuating means for the rake may be substituted for the piston and cylinder, as for instance a solenoid magnet, or movement may be imparted through a cam, crank, or lever-actuated reci rocating rod connected with the upper end of the rake, such mechanism being mounted on the beam and actuated through any mechanism which may be utilizedto suit the design of the machine.

In the construction shown in the principal figures of the drawings, the rake is pivotally mounted by a pin or bolt 23 in the outer end of a sliding bar 77 mounted between the sides 67, which may be turned in underneath as at 78 to provide a supporting base. Cross bolts 79 may also be used, passing through longitudinal slots 80 in bar 77 and through the sides, thereby providing additional bearing elements and also serving to limit the longitudinal travel of the bar, if necessary, the piston rod 76 being connected with its other end.

The rake is provided with a bearing shoulder 81 adapted to abut against the end of the bar when erected so as to prevent further movement and to maintain the rake in downward engagement with the coke during Otherwise the rake is free to fold backwardly as clearly sholwn in. Fig. 5. Ordinarily the rake will fall to operae tive position by gravity, but for the purpose of positively erecting it at any position of the beam, as when tilted, the bar 77 may be withdrawn, drawing the neck 82 of the rake backwardly against the front end 83 of the under plate 78, or against any other suitable abutment, thereby throwing the lower edge downwardly at approximately right angles or into Working position with relation to the beam.

When the rake is lowered upon the coke its upper end is then thrown outwardly and backwardly somewhat rapidly, corresponding to the quick reciprocations of the beam of the Hebb patents, until it is in engagement with the coke, when outward movement is imparted to the beam. and rake by pinion thus drawing out the coke through the door.

ifvdesired, the upper end of the rake may be pivotally mounted by a bolt 23 passing through in the sides 67, the iston rod being connected directly with bolt 23, although I refer the sliding bar construction as it provi es additional means for erecting the rake not found in this construction.

It will be understood that I do not wish to be limited. to any particular actuating, manipulating or traveling mechanism for performing the other necessary functions of an entirely o erative coke drawing machine, and it is o vious that my improvement may be embodied with various constructions, either mounted on ground or overhead tracks, within the province of the designing engineer.
